Well, theoretically, you could get that to work. But you would have to either have a REALLY NICE Domain Name host that would let you take up extra resources on their server.
You could also use a Linux server as kind of a DNS server while using special specifications in iptables:

I think if I remember my iptables correctly that would work.
Basically, users would connect to the DNS server at AntVenom.com. It would then forward the correct traffic to the destined server.
But you may also have to add a rule to allow packets to get through.
